STM32CubeMX FreeRTOS and __weak

[After Forever]

Posted on September 13, 2017 at 14:49

When enabling the FreeRTOS idle hook STM32CubeMX generates a function with the following prototype in the freertos.c file:

__weak void vApplicationIdleHook( void )

However __weak isn't defined in any one of the included header files (I'm using GCC with Makefile target) so the file can't be compiled until defining the __weak as __attribute__((weak)) somewhere.

#idle-hook #freertos

Thanks,

‌, the problem with __weak seems to be gone: after removing all those duplicate filename definitions (a new bug?) from the Makefile I was able to compile the binary.
